The engine with one overhead camshaft is mounted transversely in the engine compartment.
Toothed belt drives camshaft, high pressure fuel pump (injection pump) and water pump.
The crankshaft rotates in the cylinder block in five main bearings. Thrust half rings mounted on one of the thrust bearings are designed to adjust the runout of the crankshaft.
The engines in question use a cross-flow scheme, in which air enters the cylinders from one side of the engine, and the exhaust gases are removed from the other. With this design of the engine, the filling of the cylinders and the removal of combustion products are significantly improved.
